摘要： The present invention relates to highly efficient suction and compression rotating mechanisms, particularly the compression mechanism with piston blocks mounted on two axes and driven by a pair of matching gears in the field of compressors and vacuums or hydraulic system such as oil pump, hydraulic motor, hydraulic gearbox, specifically there is application that uses this mechanism to create one rotary motor with multi compression stages, force-generating stages and continuous fuel burning regime. The new rotary lobe structure in this invention provides a close contact between curved surfaces with the same radius, which is a “Surface-to-surface” contact, with much better tightness than “line” contact.

摘要： A power meter receives an output-voltage and a current-indicative signal generated by at least one power supply of an electronic system. The output voltage powers at least one electronic component of the electronic system. The current-indicative signal indicates a percentage of a maximum output current capacity at which the power supply is producing current. From the output voltage and the current-indicative signal, the power meter determines the input power received by the power supply.

摘要： A control circuit and method for controlling a power factor correction circuit comprising: an inductor having an input terminal to receive an input voltage and an output terminal series connected to an anode of a diode; a first capacitor connected between a cathode of said diode and ground; a first switch connected between an anode of said diode and ground; a series arrangement of a second capacitor and a parallel arrangement of a resistor and a second switch series connected with said second capacitor. The control circuit is operable to generate synchronous first and second switch control signals to respectively control said first and second switches, wherein during inrush current conditions when said input voltage drops-in after an interruption, said control circuit is operable to cause said first and second switches to be synchronously switched at increasing duty cycles. The method comprises charging a first capacitor from an input voltage source; isolating the first capacitor from the input voltage source; transferring a portion of charge stored in said first capacitor to a second capacitor while said input voltage source is isolated from said first capacitor and from said second capacitor; and repeatedly said charging, isolating, and transferring until a voltage is formed on said second capacitor that is approximately equal to said input voltage source.

摘要： A system may include a plurality of loads, a plurality of power supplies adapted to provide power to the loads, and control logic coupled to the power supplies. The control logic may determine whether output current from at least one of the power supplies to a load is below a lower threshold and, if so, may cause at least one of the power supplies to be disabled.

摘要： A method and apparatus for planarizing a substrate are provided. A substrate carrier head with an improved cover for holding the substrate securely is provided. The cover may have a bead that is larger than the recess into which it fits, such that the compression forms a conformal seal inside the recess. The bead may also be left uncoated to enhance adhesion of the bead to the surface of the groove. The surface of the cover may be roughened to reduce adhesion of the substrate to the cover without using a non-stick coating.

摘要： A SIP Gateway (SIPGW) coupled to an IP Multimedia Subsystem (IMS) is disclosed that detects when a first party, using a Plain Ordinary Telephone Service (POTS) telephone coupled to the SIPGW and participating in a call, performs a hook flash action. In response, the SIPGW sends to the IMS a first SIP INFO message indicating that the POTS telephone has performed the hook flash. In response to a first SIP INFO message indicating that a first party has performed a first hook flash, an Application Server (AS) in an IMS places on hold a second party participating in the call. The AS may also cause a Media Server to receive information from the first party identifying a call feature to be provided, where the call feature is one of simple call hold, consultation call hold, attended call transfer and unattended call transfer.

摘要： A power supply comprises an alternating current-to-direct current converter (ADC) and an input signal adapted to couple to an output signal of another power supply. The output signal is indicative of the operational status of the other power supply. The power supply further comprises logic coupled to the ADC that receives the input signal and causes an output current threshold to be increased when the output signal from the other power supply indicates that the other power supply has experienced a failure.
